SPECIFICATION forming part of Letters Patent No. 378,781, dated February 28, 1888.

Application flied May es, 1387. serai No. 239,537. No modem To all whom t may concern,.-

Be it known that I, ALBERTO FINKs, of New Berlin, in the county of Ohenango and State of New York, have invented anew and useful Improvement in Road-Machines, of which the following is a specification.

My invention is an improved road-machine, comprising a carriage or main frame, a diggerbar and scraperbar, and elevating devices therefor.

The invention consists, particularly, in the novel constructions for elevating the said bars and for adjusting the angle of the scraper-bar.

It consists, further, in certain details of construction and novel combinations of parts, as will be hereinafter described and claimed.

In ,the drawings, Figure 1 is a side elevation of my machine. Fig. Zis a top plan view thereof, the wheels being removed. Fig. 3 is a view of the front of the machine. Fig. 4 is a detail view of the connection of the upright with the scraper-bar. Fig. 5 is a detail rear view of the scraper and its attachments. Fig. 6 is a planview of such scraper and some of its attachments. Fig. 7 is a detail view of a part of the digger-bar and one of its teeth. Fig. 8 represents in detail the construction for elevating the bars. Fig. 9 is a detail view of the base-plate of the hand and sprocket-wheel support. Fig. l() is a detail side view of the scraper-bar and some of its attachments. Figs. 11 and 12 are detail views of the hounds and bolster and their attachments. Fig. 13 is a detail view of the draft-bracket, the clevis, and the connection of the draftrods therewith. Fig. 14 is a detail view of the hanger devices for elevating the digger and scraper bars. Fig. l5 is a detail view of the bearing attachments for the nprights, and Fig. 16 shows, in connection with the central steadypost, the bearing for hand-wheel for adjusting the angle of the scraper.

The main frame has side beams, A A, front beam, B, rear beam, C, diagonal cross-beam D, and short bearing-beam E, arranged between beam D and the rear side,f, of the box F. The front corners of the main frame may be braced at a by angle-plates, as shown in Fig. 2. The frame is also provided, just in rear of the beam D, with a platform, d, on which the operator may stand. The digger G has its bar g re-enforced on its bottom edge by a metallic sprocket-belts M with the wheels N.

plate, g', and the teeth G have rearwardlyprojected lugs g2, which fit in recesses g3, immediately above the said wear plate g', and the teeth are secured by clips-G2. These teeth, it will be seen, are very simple, and may be convenientlyforged. Theeentralsteady-post, G3, of this digger extends upwardly through a guide, g", on the main frame.

The scraper H has its under side and front edge concaved, and I form the said scraper with its body h of iron and its working-edge h of steel. The end uprights, H, of the scraper and its central steady-post, IF, extend upward through suitable guides, h2 on the main frame, and the end posts are connected tothe scraper by pivoting them between lugs h3, and these lugs may be arranged about midway between the upper andlower edges of the scraper; but I preferably arrange them near to the lower edge of the said scraper, as showin.

The devices for elevating the digger and the scraper are all alike. To the framing are secured the screw supports or frames I, which have openings i for the screws J and guider'ails t" for the nuts K, which are fitted at 7: to engage the rails, and are moved up and down in the frames by the screws J. Theserews have at their upper ends wheels J', by which they may be turned, and such wheels are preferably sprocket-wheels, as shown. From the nuts K depend rods or bars k', which support at their lower ends foot-pieces K', having openings kz for the passage of the lower end ofthe screws.

To the foot-pieces K are pivoted the arms Z, formed at the upper ends of links L, which are pivotcd at their lower ends to the digger or scraper, as the ease may be. By turning any one of the screws the end of the digger or scraper to which it is connected may be elevated or lowered and to any desired degree.

Each of the sprocket-wheels J is geared by These wheels have sprocket wheels or portions n and hand-wheels n', and are journaled in supports O, having base-plates O', which are slotted at o and secured by bolts o', passed through the slots into the framing, so the said supports may be adjusted from time to time to tighten the belts M. By turning the proper ones of the wheels N the scraper or the digger may be raised at either one or at both ends, as desired.

' pend from the main frame. Y brackets with front and rear wings, P P2. The

The draft-brackets P are secured to and de- I form these front wings, P', have shoulder-like portionsp p', which it, respectively, under and over the side beams7 while the rear wings, P2, have shoulder-like portions p2, which bear under the side beams, thus bracing the brackets firmly to the beam and relieving the fastening-bolts thereof in large part of the strain. Near their lower ends the brackets have openings q for the clevises Q, on the bolts q of which are se cured the drag-bars R R for the digger and scraper. The digger drag-bars R connect at their forward ends with the clevises and at. their rear ends with the digger-bars, while the scraper-drag connection It is similarly secured at its forward end, and has its rear end pivotally secured to the scraper. At the points opposite the ends of the digger-bar the connection R is bent or arched laterally outward at r, for the purpose of permitting a greater degree of endwise movement of the diggerbar, as will be understood from Fig. 2. It is also preferred to form the connection It in sections, as shown.

In order to adj ust the scraper-bar to different angles`,to arch the road-bed more or less,I tilt it onits pivotal connection with the end upright, which tilting,by reason of the concave form of the front face and lower edge of the scraper,will serve, as stated,to vary the degree of arch given the roadway. To this'end it will be seen that as the scraperis tilted back its front and lower concave edges will combine to form the surface of the roadway, which,by a proper setting of the scraper, may be arched or rounded up to any desired degree within the scope of the scraper shown. This' tilting of the scraper may also serve to accommodate it to the difficulty of the workthat is,whether the ground be hard or soft. In the construction shown this tilting ofthe scraper is effected by means of the construction which Iwill now describe.

Bearing-bars S fit, by means of boxes S at one end,on and may be adjusted longitudinally along the end uprights of the scraper, being provided with set-screws s, by which they may be clamped in the desired adjustment. These bars extend from boxes S inwardly, thence rearwardly, and make another bend outward, being provided at their extremities with openings 82, forming bearings for the screw-shaft. The boxes S have portions s3 depending in rear of the uprights, and having openings s in which the inner ends of screws T are swiveled and secured. The screw T has a pulley, t, fixed to it, and passes through and engages a threaded opening, t', in the connecting-bar T. This bar has a slot, t2, through which the scraper upright passes, and it extends past said upright and under the bearing-bar S for ward, and is connected at its forward end to the upper edge of the scraper. This connection is formed, in the construction shown, by means of a shoulder or lug,T2,depending from the connecting-bar in rear of, and a roller, T3,

journaled to said bar and bearing in front of the scraper. This roller is preferred because by it the free oscillation of the scraper is permitted, without any very great friction at the point of contact of the connecting-bar with said scraper.

In order that the scraper may be easily adj usted and that the adjustment may be equal i at both ends,I prefer to operate the adjustingscrew by means of a rope, chain, or other belt, U, passed around the pulleys t, and also around an operating drum or shaft,V, having a handle, V', by which it may be turned, and which is journaled on a shaft or stud, w, supported by a frame,\V. This frame W has preferably a box or loop-like portion, W, which fits on the central steady-post of the scraper, and may be secured at any point thereon by the set-screw w. By adjusting this support up or down on the steady-post the proper tension of the belt U may be secured.

By the described construction it will be seen that thescraper-blade may be adjusted to any suitable angle, according as it is desired to give the road more or less arch.

In this class of machines it is of great importance to provide some simple strong construction by which the slight degree of turn- I ing, which is sometimes desirable in operating the machines, maybe permitted. To thisend I provide the hounds 1,6Xed to the front axle, 2, with short elevated rails 3, on which the rollers 4 journaled to the holsters 5, turn. This construction is simple, strong, cheap, and will be found very efficient in the practical operation of my machine.

It will be understood that the digger and scraper bars suspended from the main frame may be termed the operatingbars.

Having thus described my invention,what I claim as new is 1. In a road-machine, substantially as described, the combination, with the framing and the road-making devices to be elevated, of the screw supported on the main frame and turning in a nut or threaded bearing connected with the roadmaking devices, a sprocket-v wheel on said screw, an operating-wheel, and a belt connecting the sprocket and operating wheels, substantially as set forth.
